Loosen the aiming bolts (A) a little at a time, and remove the millimeter wave radar (B) from the main bracket (C).
NOTE:
Do not disassemble the millimeter wave radar.
If you disassemble the main bracket, always use new screw grommets (D).
Install new screw grommets on the millimeter wave radar. Position the left side grommet grooves (E) horizontally, and position the right side grommet groove (E) vertically.
Tighten the main bracket bolts a little at a time until the clearance between the millimeter wave radar and the main bracket is 16 mm (0.05 ft) (F). Make sure the millimeter wave radar is parallel with the main bracket.
Clean the surface of the millimeter wave radar (G).
